Row monitoring.For example, when the picture for being gathered by camera head 22 finds that photovoltaic panel has breakage, can be according to the photovoltaic for having breakage
The running state information of plate judge photovoltaic panel whether can normal work, so that it is determined that damaged degree.
It is that monitoring terminal 3 is by comparing aircraft 2 to one embodiment that photovoltaic panel is monitored using monitoring terminal 3
The thermal imaging picture of transmission and benchmark thermal imaging picture, judge whether the caloric value of photovoltaic panel is normal；Or by comparing flight
Picture and reference base picture that device 2 sends, judge whether photovoltaic panel needs to clean.
In thermal imaging picture, using the temperature of different color mark objects.For example, in part thermal imaging picture,
The corresponding temperature in cool colour part is higher than the corresponding temperature in warm colour part.It is therefore possible to use image processing techniquess compare flight
The thermal imaging picture of the transmission of device 2 and the difference degree of the color of relevant position in benchmark thermal imaging picture, so as to judge photovoltaic panel
Caloric value whether normal, and then judge in photovoltaic array, whether to have the condition of a fire, photovoltaic panel whether to break down etc..
Picture and the feature of reference base picture that monitoring terminal 3 can be shot by extraction camera head 22, and according to feature
Comparison and matching result judge photovoltaic panel whether need cleaning.
Another kind judge photovoltaic panel whether need cleaning method be：First, aircraft 2 projects sine streak to photovoltaic panel
Image；Then, the CCD (Charge-coupled Device, charge coupled cell) in the camera head 22 that aircraft 2 is carried
By the reflection receivable of photovoltaic plate surface to these black and white strip images, picture is generated；Finally, monitoring terminal 3 is received and is processed
The picture that aircraft 2 sends, obtains the phase diagram of picture, can obtain the song of photovoltaic plate surface each point after integral operation
Rate.The curvature of the curvature of the photovoltaic plate surface each point of the picture that aircraft 2 is sent and the photovoltaic plate surface each point of reference base picture
It is compared, you can find whether photovoltaic plate surface needs cleaning.
It is thus possible to find the defect of photovoltaic plate surface, such as convex-concave point, abrasion, fall at paint etc..
